SPECIFICATION forming part of Letters Patent No. 740,33L'dated Septemberl 29, 1903.

' Application filed February 3,1903. Serial No. 141,629. (No model.)

To a/ZZ whom t 'ma/y concern.'

Be it known lthat .L SYLvEsrER ScrIrTs, a

'citizen of the United States, and a resident of Ironton, in the county of Lawrence and State of Ohio, have invented a new and Improved Trolley, of which the following is a full, clear,

and exact description.

This invention relates to a means for facili- .tating the lubrication of trolley-wheels; and

it comprises certain novel devices enabling grease or any other lubricant to be used and to be pressed steadily into the bearing of the trolley-wheel, thus keeping the wheel coustantly lubricated.

This specidcation is an exactdescription of one example of 'my invention, while the claims define the actual scope thereof.

. Reference is' to be had to the accompanying drawings, forming a part of this speci tication,

in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the invention. Fig. 2 is a longitudinal section thereof, and Fig. 3 isa section on the line 3 3 of Fig. 1.

a. indicates the trolley-pole, which is securely fastened into a hollow harp-section b.

` Said section b is open at the end opposite the pole a and is screw-threadedthereat to receive the threaded portion c' of the outer or second harp-section c. Cotter-pins or other readily-removable fastening devices d (see Fig. l) are employed for holding the parts b and c againstA disconnection. In the outer harp-section c is formed a grease-chamber c2, and working in this chamber is a piston or follower e, the stem e' of which is threaded,

` as shown, and passes loosely through a clog indicates the trolley-wheel, and h the axle thereof. This axle projects between the arms'f and is securely fastened therein by a pin it', connecting the right-hand arm fand axle h.- Said axle is formed with a longitudinal passage h2, which opens at the left-hand end ofthe axle, 'and said left-hand end is screwed ox" otherwise fastened to the lefthand arm f, so that the passage h2 communicates with and, indeed, forms acoutinuation 6o of the passage f. The axle h also has a series of transverse passages h3 passing from the passage h2 laterally to the outer side ot' the axle, so as to lead the grease or other lubricant into the bearing of the trolley-wheel. The duct f may be provided with any suitable means for regulating the amount of grease forced therethrough, this means being, for example, after the nature of a needlevalve or the like operating in the duct. Con- 7o tact is made from the ends of the wheel-hub to the respective arms f and thence through the harp-sections to the .pole a or to any other suitable conductor.

In order to llthe grease cup or chamber c2, it is only necessary to disconnect the secf tions b and c, unscrew Athe closure c3, and

draw vout the follower e, with the parts attached thereto. After iilling the chamber c2 the screw-stem e should be turned in the nut 8c e2, so as to move and hold the follower e in close proximity with the closure c3. When this is done, the closure should be again applied, as shown in Fig. 2, and then the nut e2 should be screwed back toward the lower end 8 5 of the stem e', thus rendering the nut inactive and allowing the spring eS to exert a steady pressure on the grease or other lubricant and force thesame continually through the duct f to thetrolley-wheel. 9o

It will be understood that while the device is adapted especially for use in connection with grease or semiliuid lubricants it may nevertheless be used for heavy oils, all of which will suggest itself to skilled mechanics.

Various changes in the form, proportions, and minor details of my invention` may be resorted to at will'without departing from the spirit and scope thereof. 'Hence I consider myself entitled to all such variations as may roo lie within vthe intent of my claims.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. The combination of a trolley-wheel, a harp on which the wheel is mounted,said harp being formed in two sections having removable connection with each other and the section carrying the harp having a lubricantchamber therein and a duct leading from the lubricant-chamber to the wheel-bearing, a follower mounted to move in the lubricantchamber, a stein connected with the follower and projecting past the inner end of the harpsection having the lubricant-chamber into a 'cavity in the other harp-section, and a spring pressing the follower.

2. The combination of ahollowinner harp` section, an outer harp-section having a lubricant-chamber therein and removably connected with the inner section, a closure for the inner end of the 'lubricant-chamber, a follower in the lubricant-chamber, a stem connected with the follower and projecting through said closure, a spring pressing the follower, and a trolley-wheel mounted on the outer harp-section, said section having a duct extending from the lubricant-chamber to the bearing of the trolley-wheel.

3. The combination of a trolley-wheel, a harp on which the wheel is mounted, said harp havinga lubricant-chamber and a passage leading from the chamber to the wheelbearing, and means for exerting continuously a pressure on the lubricant to forceit through the passage.

4. The combination of a trolley-wheel, a harp on which the wheel is mounted, said harp having a lubricant-chamber and a passage leading from the chamber to the wheelbearing, means for exerting continuously a` pressure on the lubricant to force it through the passage, such means comprising a follower, a stem attached thereto, a stop-nut on the stern, and a spring pressing the follower.

5. The combination of a trolley-harp havinga lubricant-chamber therein, and an arm projecting from the harp, the harp also having a passage extending from the lubricantchamber through the arm, a hollow axle held by the arm and having alateral perforation, a trolley-wheel carried on the axle, and means for pressing continuously on the lubricant to force it into the hollow pin.

6. The combination of a trolley-harp in two sections one of which is hollow and open at 'one'end, and said sections being connected at the'open end of the hollow section, a trolley-wheel mounted on the harp, the harp having a passage leading from said hollow section to the wheel-bearing, a closure fastened in the open end of the hollow section, a follower working in the hollow section, and a spring acting between the follower and closure.

7. Thecombinationofatrolley-harpformed in two sections, said sections being in longitudinal alinement with each other and joined together intermediate the ends of the harp, one of said sections being hollow and open at one end, and the sections being connected at the open end of the hollow section to inclose said open end, and a trolley-wheel mounted on the harp, the harp having a lubricatingpassage extending from the hollow harp-section to the wheel-bearing, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
